minimization of total mechanical rotary energy required for high-pressure natural gas transmission using thermodynamic optimization

Efficient energy utilization in high-pressure natural gas transmission system is vital for sustainable and cost-effective operation of gas supply chains. this study presents a simple thermodynamic optimization framework to minimize the total mechanical rotary energy required by turbo compressors in long-distance natural gas pipelines. the optimization is based on the analytical formulation, where the goal is to minimize the total rotary energy requirement. the proposed model accounts for real-gas behavior through the compressibility factor, adiabatic efficiency and thermo-dynamical parameters of the working gas. parametric sensitivity analysis reveals that optimizing the pressure and maintaining high adiabatic efficiency significantly reduce energy demand. the findings provide a foundation for energy-efficient compressor station design and operation within modern natural gas supply networks.
